OVERVIEW
Description
Advanced UL 508 Seismic Switch — Intelligent Earthquake Detection for Industrial Safety
High integrity switch offers economical 24/7 protection
Engineered for performance, reliability, and compliance, the Advanced UL 508 Seismic Switch is the ultimate solution for industrial and commercial earthquake protection. Designed to meet UL 508 and NEC electrical code standards, this intelligent plug-and-play seismic switch provides instant, real-time earthquake detection to safeguard critical systems and ensure uninterrupted operations.
Built with a solid-state digital tri-axial sensor, the system continuously monitors ground acceleration (PGA) across all three axes—X, Y, and Z—to deliver precise and immediate seismic response data. Its advanced filtering technology eliminates false triggers caused by nearby vibration sources such as machinery, trucks, trains, or compressors, ensuring that only genuine seismic activity initiates protective actions.
Key Advantages
-
UL 508–Certified Design – Built to the highest standards for industrial control panels and electrical safety.
-
Triple Relay Control – Three independent Form C outputs with dry, isolated contacts for flexible integration.
-
Uninterrupted Operation – Equipped with a battery backup and external charger for continuous power during outages.
-
Customizable Sensitivity – User-selectable trigger levels tailored to local seismic intensity requirements.
-
Smart Reset Options – Operates in latched or automatic timed reset mode (1–60 seconds) for different safety scenarios.
-
False-Trigger Protection – Advanced filtering and digital logic provide exceptional immunity to non-seismic vibrations.
Built for the Toughest Environments
From refineries and manufacturing plants to rail networks, power stations, and data centers, the Advanced UL 508 Seismic Switch provides a maintenance-free, intelligent safeguard that activates instantly during seismic events. Its rugged design and dependable operation make it ideal for mission-critical environments where downtime is not an option.
Reliable. Compliant. Intelligent.
The Advanced UL 508 Seismic Switch is more than just a detector—it’s a guardian for industrial safety, ensuring your equipment and personnel remain protected when every second counts.

SPECIFICATIONS
Technical Specifications
| Sensors | Solid state, triaxial accelerometer in three orthogonal axes. Detects vertical “P” and horizontal “S” wave earthquake acceleration (X, Y & Z axes). Stores and displays Peak Ground Acceleration (PGA) values on each axis, in “g” when triggered.* |
| Frequency Response | 1 Hz – 10 Hz or, 1 Hz – 15 Hz as programmed. Sensor filters non-earthquake (industrial) vibrations. User-adjustable for ASCE 25-97, ASME A17.1 & CA3137 trigger response. |
| Setpoints | User selectable from 0.025g to 0.5g on each axis (X, Y & Z). Terminal communication program supplied with instrument. |
| Communications | RS-232C serial (3-wire) or USB for programming & PGA data recovery. |
| Diagnostics | Power-On Self-Test (POST) and diagnostic commands. |
| LED indicators | “Seismic Trip”; via internal LED indicator and integral lamp in front panel Test/Reset switch. |
| Seismic Activation | Front panel visual indicator, Form C relay contacts. |
| Control Output | Three independently programmable alarm output control relays. Form C, dry, isolated alarm relay contacts rated 4 amps @ 250 VAC). Unit provides one (1) common fault alarm (power or sensor) and two (2) seismic alarms. Following a seismic trip, system can automatically reset after delay OR remain latched until manually reset via front panel switch. |
| Power Supply (UL) | 120 VAC, 50 / 60 Hz or 220 VAC, 50 Hz (specify). Rechargeable 12 VDC, 1.2 Ah Sealed Lead Acid battery. 1+ hr reserve at maximum demand. External charger. |
| Physical | Size, 8″ W X 8″ D X 5″ H; 9 lbs (19 lbs w/ mounting plate) Enclosure NEMA 4 standard. Options include: NEMA 4X, bypass switch and/or vertical mount Sealed cable and conduit entry fitting. Operating temperature, -20º C to + 70º C. Humidity, 0% – 95% (non-condensing). |
| Installation | Via four ¼” bolts (one bolt for optional plate), rigidly attached directly to building slab or other large, inertial seismic mass. Mounts horizontally. Vertical (wall-mount) unit optionally available. |
